7 Claims.

This invention relates to web splicing or pastor devices for newspaper presses in which a web from a fresh roll of paper is applied or adhesively connected to the web from a nearly exhausted roll of paper and an object is to produce a new and improved method and apparatus for splicea ing such paper webs together during the operation of the press at full press speed in such manner that an eificient and satisfactory paster is eifected without loss of time and with a minimum of paper waste and in a simple and efficient manner;

Other objects and advantages of the invention will hereinafter appear and for purposes of illustration butnot of limitation, an embodiment of the invention is shown on the accompanying drawings in which Figure 1 is a side elevation partly diagrammatic of a reel for paper rolls showing the mechanism for splicing the web of a new paper roll to the web from a roll which is substantially exhausted, the parts being shown substantially atthe time when the web from the exhausted roll is severed;

Figure 2 is a partly diagrammatic view showing a side view of a paper roll and the driving wheel for driving the paper roll at press speed disposedin inoperative position;

Figure 3 is a View somewhat similar to Figure 2 showing the driving wheel in driving contact with the paper roll;

Figure 4 is an enlarged view partly in section and partly diagrammatic showing the web severing mechanism; I

Figure 5 is a sectional view substantially on the'line 55 of Figure 3 with some of the parts omitted for purposes of clarity to illustrate the connection between certain of the parts and the spring cable arrangement which urges the cam disc to its depending position; and

Figure 6 is a wiring diagram showing the electrical circuit controlling the operation of the several parts.

The illustrated embodiment of the invention comprises a standard H) on which a three-arm reel H is rotatably mounted. Suitably carried by the arms of the reel H are fresh paper rolls A and Band aroll C, the paper web ofwhich is substantially exhausted. The reel is driven in any suitable manner from an electric motor l2 so that the reel can be rotated in a counterclockwise direction for bringing fresh rolls or successively the rolls B and A into operative position,

the roll C being shown in the operative position or the position assumed when the web suchas the web I3 leading from the roll C extends to the newspaperpress (not shown). I

At the proper time; the oncoming'roll or the roll whose web is to replace the web from ,the exhaustedroll is driven bya wheel It which has a friction producing rim l5 such a rubber or other suitable matcrial. The wheel M is brought into contact with the end of the roll such as the roll B in the form shown near the peripheral surface thereof about one-eighth inch therefrom. The wheel M isdriven' in any suitable manner from the newspaper press so that the paper roll B is driven thereby at press speed. The wheel 14 is mounted on the outer end of an arm [6 the upper end being pivotally connected to an arm 11, the latter having an extension i8 and interposed between the' freeyend of the extension 18 and'the arm it is a coil spring i9. On the opposite end of the arm- H'is an upwardly and outwardly inclined portion 20 on the free end of The roller 2| enwhich is disposed a roller 2|. gages the outer surface of a cam disk 22. The cam disk 22 is eccentrically' mounted about a pivot 23; In diametrically opposedrelation to the axis 23 of the cam disk 22 is a pin 24 which is engageable by an arm 25 having a notched outer end. y

In the normal position of the parts as shown on Figure 2 in which the driving wheel I4 is disposed in inoperative position, it will be noted that the pin 24 is lowermost and is engaged by the notched arm 25. The notched arm 25 is sliitably connected to a shaft 26 having an operating handle '21. By actuating the handle 21, the arm,

25 may be swung in a clockwise direction (Figure cam disk 22 and raising it to the position shown in Figure'S, whereupon the notched end of a lever 28 engages the pin 24 and hold the cam disk 22in such position. After the cam disk 22 has been raised and the notched lever 28 has engaged the pin 24, the operator releases the handle 21 which thereupon swings downwardly to its normal position, returning the arm 25 to by operatively to drive the roll B. The opposite end of the lever 28 is connected to a solenoid generally'indicated at 29, a spring 30'normally urging the arm 28 into pin-engaging position. It will be apparent that upon energizingrthe as 2), thereby imparting similar movement to the I solenoid, the arm 28-isrocked sufilcientlyto cause the arm 28 to release the pin 24 and the cam disk 22is returned to normal position being normally urged to such position by a spring cable 3|, the outer end of which is suitably connected to a sheave 32. It should be noted that the above described parts are mounted on a bracket 33 which is suitably suspended from supporting rods 34.

In operation, the free end of the oncoming roll such as the roll B is coated with adhesive and at the proper time the reel ll is rotated in a counterclockwise direction to bring the pasted end into engagement with the web l3 from the exhausted roll 0. During such movement of the reel, the paper roll B is moved into contact with a relatively soft composition roll 35 which is carried by a bracket arm 36. Movable with the bracket arm 36 is a sprocket wheel 31 which is connected by a chain 38 to a smaller sprocket wheel 39 fixed to a sheave 46. Secured at one end to the sheave 46 is a cable 4! to the lower end of which is a relatively small weight 42. The cable extends through an opening in a larger weight 43 which is moved upwardly by the weight 42 when the sheave 40 is rotated in one direction. The larger weight 43 has a sheave 44 at its upper end which is connected by a cable 45 to a sheave 46 having a .weight 41. In opposed relation to the sheave 44 is a sheave 48 having a cable 49 which extends upwardly over a sheave 56 and thence downwardly to a sheave to which is fixed a sprocket wheel 52. Over the sprocket wheel is trained a chain 53 the lower portion of which passes around a sprocket wheel 54 and then extends upwardly through a guide housing 55 the upper end thereof being connected to a carriage 56. The portion of the chain 53 which extends downwardly from the sprocket 52 is secured at 5'! to the carriage 56. The carriage 56 is movable up and down in the guide housing 55 and is provided with a laterally extending bracket 58 on which is pivotally mounted a bell crank 59 on one end of which is mounted a roller 66 the other arm 6! of which being adapted to extend outwardly from the housing 56 a substantial distance to engage the web l3 and break or sever it from the exhausted roll C. The bell crank 59 is normally urged to the position shown in Figure 4 or to web severing position by a coil spring 62 one end of which .is anchored to the bracket 58 and the opposite end of which is connected to the arm 6|. Extending outwardly from the bell crank substantially in alignment with the roll carrying arm and secured by movement therewith is .a trip arm 63 which is adapted to be engaged by a catch lever 64 which is notched to receive the arm 63. The catch lever 64 is pivotally mounted at 65 on the carriage 56 and is urged outwardly or into arm engaging position by a coil spring '66. The solenoid 6'! is associated with the catch lever 64 and is adapted when energized to swing the catch lever 66 to the left of Figure 4 to release the arm 63.

When the carriage 56 is moved upwardly its upward movement is limited by an arm 68 which is connected to the lower end of the carriage 56 and projects outwardly a sufficient distance to engage the underside of the exhausted roll C so that the web severing arm 6l is disposed in the desired position for severing the web l3. The stop arm 68 functions to hold the severing mechanism in the desired position but the severing operation takes place subsequently. When the carriage 56 is moved downwardly the roller 60 on the bell crank 59 engages a stationary cam track 69 which is so designed as to rock the bell crank 59 in a counterclockwise direction sum ciently so that the arm 63 is moved into latching engagement with the catch lever 64.

A notch is formed in the rear face of the carriage 56 adjacent the lower end thereof and is adapted to receive an arm H for retaining the carriage in its lowermost position. The L- shaped arm II is controlled by a solenoid 12 which, when energized, swings the L-shaped arm ll outwardly to release the carriage 56 to allow the same to move upwardly for effecting severance of the web l3.

Rotatable with the roll B is a disk '13 of fibrous or other suitable non-conducting material and carried thereby is an elongate plate 14 of copper or other suitable conducting material. The plate 14 is adapted to engage contact and 16 carried by a stationary post 1'! for a purpose which will hereinafter appear.

In operation of the above described mechanism, the reel II is first rotated in a counterclockwise direction so that the roll Bis at a predetermined distance from the travelling web [3, adhesive having been previously applied to the new'roll. About one inch spacing is sufficient. Thereupon, the handle 21 is actuated to bring the driving wheel i l into operative engagement with the end of the paper roll 13. This same operation causes the solenoid 12 to be energized thereby to release the carriage 56 permitting it to move upwardly in the guide housing 55 into operative position relative to the exhausted roll C. As shown on Figure 6, when the handle 21 is moved to bring the driving wheel it into operative position, the turning movement of the shaft 26 in which the handle is mounted, closes, through any simple mechanical connection, the switch 85, one terminal of which is connected by a lead 86 to the solenoid l2. Extending from the solenoid 12 is a lead 81 which is connected to one pole of the current source, as indicated. The other terminal of the switch 85 is connected by a lead 38 to the other pole of the current source. It will be understood that when the handle 2'! is moved in this manner, the contact member 18 on the extension l6 of the arm [1 is moved away from the contact elements 19.

Thereupon, the paster button or control button 86 is depressed to release the latch lever 28 to enable the driving wheel 14 to move away or swing by gravity away from the paper roll 13. As shown on Figure 6, depression of the paster button 86 closes a circuit comprehended by the lead 81 and a lead 89 which joins the solenoid 29 and then connects with the lead 88, thereby energizing the solenoid 29 which actuates the lever 28 to release the cam disc 22 which allows the driving wheel Hi to swing away from the paper roll. After the driving wheel [4 has moved a sufiicient distance away, the contact member 18 on the extension I8 of the arm 11 engages the contact elements '19 and, through the following described connections, energizes the reel motor I2 causing it to turn in a counterclockwise direction (Figure l), but before that action can take place, the contact arms 15 and 16 must first have engaged the conducting plate 14 on the rotating disk or paster timer 73, the contact arms being connected through suitable relays to complete the circuit to the motor 12. In this connection, it will be observed in Figure 6 that the first revolution of the paper roll B brings the contact plate 14 into engagement with the contact arms 15 and 16, thereby closing a circuit which includes a lead 96 connected to the lead 89, a lead 9|, relay switch 92, lead 93, solenoid coil 94, lead 95, and

contacts 19 which have previously been connected by the contact member 18 and finally lead 96., Energizing of the solenoid coil 94 operates to pose, it will be understood that, at the same time the solenoid M is energized, a solenoid N13 is en ergized by a circuit including a branch lead Hi4,

which extends to one pole of the current supply as will be apparent, and a branch lead, H15, which extends to the other pole of the current supply through leads M95295, contacts 19, contact member l8 and. lead 96. The solenoid N13 is preferably of the usual delayed action type, so that movement of the switch 92 from its normal position in engagement with the contact I06 into engagement with the contact Ill'l, is delayed. Thus itwill be apparent that the switch 92 is brought into engagement with the contact Iil'l when'the contact plate"! makes its second revolution, so that when the plate 14 engages the contact arms 15 and IS, the second time, current then flows through the lead 9!) from the connections de scribed, through the lead 9!, switch 92, contact 1 ill, lead 38, solenoid 61, and lead Mil to the lead 38. It will be noted that after the contactplate M in its first revolution has passed over the contacts 15 and 76, current is still supplied to the solenoids 94 and H13 through the lead lil, control button or switch 88, lead 9ll, s\vitch 99. lead llEl, solenoid 94, solenoid H13 which is con nected in parallel withsolenoid M, lead 95 and Thereafter, the roll B abutting ag inst the soft composition roll 35 swings thetlatter outwardly and through the connections above described lifts the weights and allows the carriage 56 to lower to such position that it, is caught by the L-shaped arm 1 l for the next operation. The paster button or switch til is then released, whereupon the solenoids 94 and I03 are de-energiZedbreaking the circuit to the reel motor l2, and the paster operation is thus completed,
